What is Cross browser testing?
Cross browser testing is the process of reviewing and comparing website functionality and styles across multiple browser platforms, operating systems, and mobile devices to uncover any potential discrepancies.
We all have a preferred browser that we use daily, so it can be easy to forget what the rest of the population is using to access a website. Whether you’re a developer, designer, or quality control inspector, you have to consider the countless methods end-users can utilize to interact with your website
Why Cross browser testing is performed?
To check whether appearance of web pages in different browsers- is it the same, is it different, if one is better than the other, etc. and also functionality and working of it.
One of the main aspects of cross-browser testing to keep in mind is that CSS styles render differently across browsers/browser versions, especially in terms of what is supported and what is not. Older versions of Internet Explorer are generally the most affected by unsupported CSS elements and newer HTML tags.
